2 Why Did President Bush Suddenly Start Talking about Standby Power? Alan Meier Lawrence Berkeley National Laboratory

3 2 Standby Energy Use and Energy Savings Opportunities 1.Why did President Bush get interested in standby power? 2.How large is standby power? 3.Savings opportunities

4 President Bush Saw This Display…. And wrote an Executive Order about standby …

5 4 How Large Is Standby?

28 27 How Large Is Standby? 5% of residential electricity (~50W) –20 appliances/home –TVs and VCRs down, but number up –No estimates for commercial & industrial Similar levels in other Europe, Japan –Urban Chinese homes: ~30W already! ~1% of global CO 2 emissions

29 28 Reducing Standby Power 3 examples…

30 29 Case Study: Internet Appliance

31 30 Internet Appliance Savings

32 31 Satellite/Internet/DVR Box Microprocessor Power Supply “OFF” - 17 WattsON - 21 Watts Thermographs of

33 32 The 2002 Calypso Washer. It’s bigger, better… and it uses 1/10 the standby power of Neptune.

34 33 Reducing Standby Power Components –Low power components (include displays) Design –Don’t energize unneeded components Power Supply –Reduce no-load loss –Improve efficiency at low loads –Move switch to high-voltage side
